});
Auth::routes();

Route::get('/home', 'HomeController@index')->name('home');

I have tried this too but still the same.

<td> {{$department->name}}</td>

@foreach($departments->name as $department)
<td> {{$department}}</td>
@endforeach

In your web.php,
replace this:

Route::get('/dashboard', function () {
    return view('admin.dashboard');
});

with this:

Route::get('/dashboard', 'AdminDashboardController@index' );

In you Dashboard controller, replace this:

public function index()
{
    $users= User::all();
    $departments = Department::with('users')->first();
   // return view('admin.dashboard')->with('departments',$departments)->with('users',$users); 
    // $departments = Department::with('users')->where('users.department_id','=','departments.id')->first();
    // dd($departments);
     dd($users); 
    // return view('admin.dashboard',compact('departments','users'));        
}

with this:

public function index()
{
    $users= User::all();
    $departments = Department::with('users')->get();
    return view('admin.dashboard',compact('departments','users'));        
}

```
Route::get('/dashboard', function () {
    return view('admin.dashboard');
});
```
Here’s your problem. You’re returning the dashboard view without passing it the list of departments.

This route should be using the DashboardController@index ( and your commented code should be uncommented) – which gets the list of departments and returns the view while passing in the list.

Better yet if you used the URL /departments and a DepartmentsController…

can you try this? see if it changes the error?


use AppUser;
use AppDepartment;

Route::get('/dashboard', function () {
    $users= User::all();
    $departments = Department::with('users')->get();
    return view('admin.dashboard',compact('departments','users')); 
});

comment out this.

// Route::get('/dashboard', 'AdminDashboardController@index' );

Also in you balde file you need to chenge to this, this will give you all the department.

              @foreach($departments as $department)
              <td> {{$department->name}}</td>
              @endforeach

Update

<?php

namespace App;

use IlluminateDatabaseEloquentModel;

class Department extends Model
{

    protected $table = 'departments';
    protected $fillable = [
        'name',
    ];
    protected $primaryKey = 'id';

public function users()
{
    return $this->belongsTo(User::class);
}

}

Try changing the User model to have the following relation:
```
public function department()
{
    return $this->belongsTo(Department::class);
}
```
In DashboardController change it to the following:
```
class DashboardController extends Controller
{
   public function index()
   {
     $users= User::all();
     foreach($users as $user)
     {
       echo $user->department->name;
       echo $user->name;
     }
  }
}
```
And update the associated route:
```
Route::get('/dashboard', "AdminDashboardController@index");
```
